It's a fact that 32-bit Pan runs out of *process* address space at
around 2GB. 64-bit Pan doesn't technically have that problem, but
effectively it does, although it does for all practical intents.
Well, the 32-bit part isn't quite accurate, or at least it's accurate
for only a subset of 32-bit.
It's completely accurate for the set of people who use pre-built Debian
and Ubuntu kernels.
You mean they don't have a 32-bit "enterprise kernel" or perhaps a
"enterprise/database kernel" or similar, with the 4G/4G userspace/
kernelspace option enabled? Given that database-server targets have
been, by my reading, the primary use of such a config, I'd have expected
they'd have at least one such kernel option available.

But perhaps it is accepted that such "advanced server usage" requires a
reasonably good sysadmin, where "reasonably good sysadmin" is defined in
part as having (or at minimum, knowing where/how to get) the knowledge to
properly reconfigure and rebuild the kernel with that option enabled, if
they need it.
I'm going to bet that all database servers in the last 5 years are
64-bit, so your theorizing is moot.
